www.rolfvanmeurs.nl by Rolf van Meurs: This website uses a simple global navigation with short and clear page names. Important topics are placed on the left side and less important topics such as Links and Contact are placed on the right side of the navigation.
www.netmums.com by Net Mums: This website uses nice tabs with different colours for each section. If you use tabs make sure the active tab is visually in front of the other tabs. The active tab should also use the same colour as its sub navigation.
www.wix.com/mussani/sempurnaexpresscargo by Sempurna Express Cargo: The three coloured teasers seem to be part of the navigation. I would expect to get more information about the liners, the pick up/delivery or the services behind these teasers. But the three images all link to the same site, which doesn’t offer much more information. If something seems clickable you must make it clickable and link to more information. Otherwise you will mislead your site visitors.
